FIREPLACE-DAMPER.

Specification of team Pat ent. P tent d N 1 1, 1913.

Application filed Ma 5, 1912.- Serial No; 765,703.

To all whom it may concern:

Be it known that 1, PAUL A. DELSING, a

citizen of the United States, and resident of the city of Seattle, county of King, and State of Washington, have invented certain new and useful Improvements in F irepl'ace- Dampers, of which the following is a speci- 1 the reception of the pivot journals 11 of My invention relates to fire place dampers and comprises certain novel features which 1 fication.

will be hereinafter described and particularly pointed out in the claims.

The object of my invention is to produce I a fire place damper having features of sim- 1 plicity, cheapness of cost, ease of adjust- Q ment, strength and durability, and of supei riority in other lines, which will give it material advantages over fire place dampers through holes formed in ears or lugs 12,

In the accompanying drawings I have shown my invention embodied in the form I The damper has an operating arm 3, se-

as generally constructed.

which is now most preferred by me.

Figure 1 shows the damper, complete,

ready for installation, but separate fromf the fire place, the view being a perspective taken from a direction to. show the inner side of the damper, or that which faces toward the back of the fire place. and 8 are transverse sectional elevations, Fig. 2 showing the damper in closed position while Fig. 3 shows -.the damper as partly raised.

The manner of making this damper, is to mount it upon a length of angle iron, or which forms the foundation or frame member for the damper and also the supporting beamfor the fire place lintel. The damper, so mounted, is a self-contained structure which may be assembled in the shops and requires but little labor to put it in place. It is however, evident that the foundation plate or frame might, if made slightly shorter, be applied to a fire place after it has been built.

The frame member herein shown consists of the angle bar 2, which is made of such length as to span the fire place opening and rest upon the walls at each side, and is of such weight as will enable it to properly support the masonry imposed thereon. The web of this beam is the one upon which the brick of the fire place lintel is placed, the web 21 extending upward close against the inner surface of the front wall. The pivot bearings for the damper are mounted upon the upper edge of this inner, vertical Figs. 2

'the operating bar proper.

web 21, the means shown for mounting the damper consisting of two pairs of bars 5 and 50, secured to the web 21, so as to come even with the ends of the damper. The rearmost bar -,l1as its upper end bent back, or toward the rear, so as to form, with the other bar 5, an upwardly opening yoke for formed by cutting the. end of the plate and turning a section thereofupward.

cured thereto at about the middle of its length and extending downward until 1ts lower end is accessible from without the fire place: I have shown it as extending slightly below the-lintel, where it may be engaged by -the foot, or anyv convenient tool, to throw the damper backward and upward, the extent of this movement depending upon the vigor ofthe kick, or the distance which it is pushed back. This operating arm should be made of substantial construction, so that it will not become bent out of shape by use.

I have shown it as made of a substantial bar of iron bent into the form of a bracket, of which one arm, 31, is secured to and extends transversely of the damper, thus forming a reinforcement for the damper plate, and the other arm, 30, extends downward and forms The operating bar 3 is further strengthened by a brace bar, 32, which connects the parts 30 and 31. The lower arm 30, is provided with a horizon tally and transversely extending surface, adapted to be engaged by the teeth of a holding bar 4, by which it is held in adjusted position. This is preferably done by providing the arm 30, with a slot for the reception of the holding bar 4, which also serves to securely hold these two members in proper relation. The holding bar 4 is pivoted at the under edge of the lintel and extends a short distance outward, or toward engagement of the teeth thereof from the arm.30 by ressure applied from outside, Its inner enc is provided'with a hook, 42-, or in other way is prevented from disengagement from the arm 30.

Whether the damper drops down to the closed position, or stops in a partly raised position, will depend upon howquickly the bar 4 is released after being raised. It is possible, by giving the bar only a quick touch, to drop the damper one notch or tooth at a time. The operating arm being at the center of the length of the damper, all efiort [applied thereto is balanced and no warping per plate centrally of its length and extending downward to below the lintel level, a holding bar pivoted beneath the lintel and. having a short end extending outward from its pivot .for operative: engagement and having a longer toothed end extending backward from its pivot and with its toothed edge engaging by gravity the controlling arm of the damper plate; 7 i

2. ,In a fire place damper, in combination, a

lintel-supporting bar, pivot bearing members secured to said lintel-supporting bar and extending upward back of the lintelto locate their bearings well above the lintel and next the outer wall of the throat, a damper plate having pivots on one edge fitting within said bearings, a controlling bar secured to said damper plate centrally of its length and extendingdownward to a point below the lintel, the lower end of said controlling bar being slit, and a holding bar pivoted at the 45 under edge of the lintel and extending through the slot in the controlling bar, the under edge of said holding bar being toothed to engage and hold the controlling bar when the same is pushed back.

3. In a fire place damper, in combination, a lintel-supporting bar of angle cross section having one flange extending upward along the inner wall of the arch, the said bar being of a length to extend beyond the sides of the fire pla'ee opening, pivot bearing members secured to said bar with their bearings well above the lintel and at the lateral edges of the fire place throat, a damper plate having end pivots in line with one side edge and adapted to be carried by said pivot bearing members, a controlling bar extendingdownwardly from the pivot edge of the damper plate and centrally of its length, a locking or holding bar pivoted upon the lintel-supporting bar and having a toothed edge engaging by gravity the controlling bar to hold it in adjusted position.

In testimony whereof I have hereunto affixed my signature this 28th day of April, 1913.
